Any hospital or facility in which surgery and other invasive procedures are performed should have accommodations for cleaning, decontaminating, disinfecting, and sterilizing instruments, equipment, and other essential supplies that are used for patient procedures. Sterilization is essential to reducing or preventing the risk of surgical site infections. This is a collaborative process and should include all health care providers who handle these instruments, including perioperative nurses. The revised AORN "Recommended practices for sterilization," which became effective June 15, 2012, includes updates on sterilizing single-use items, inspecting critical items before sterilization, using low-temperature hydrogen peroxide vapor sterilization methods, and immediate use steam sterilization. This RP document is the first AORN document to be evidence rated and accepted for inclusion in the Agency for Healthcare Research and Quality National Guideline Clearinghouse.
